Hi folks, I'm trying to use the BIO routines with openssl-0.9.5a I need a idea encryption filter so, after creating this one I used the BIO_set_cipher but I'm not able to make it works.... this is my code: if ((benc=BIO_new(BIO_f_cipher())) == NULL); BIO_set_cipher(benc,(const EVP_CIPHER *) EVP_idea_cfb,key,iv,1); in this way, calling BIO_set_cipher, I obtain a sigsev even when benc is != NULL. Then I tried if ((benc=BIO_new(BIO_f_cipher())) == NULL); cipher=EVP_get_cipherbyname("idea-cfb"); BIO_set_cipher(benc,cipher,key,iv,1); and if ((benc=BIO_new(BIO_f_cipher())) == NULL); cipher=EVP_get_cipherbyname(LN_idea_cfb64); BIO_set_cipher(benc,cipher,key,iv,1); but cipher is always NULL. where am I wrong???? max liccardo ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List [EMAIL PROTECTED] Automated List Manager [EMAIL PROTECTED]
